"We must be the change we wish to see in the world." The participants in this ground-breaking program come from different backgrounds, but hold common values, beliefs and goals. They all want to effect change in our world by helping others.

CNN has equipped a group of volunteers with cameras, laptops and a brand new Web site. They will blog and post videos of their lives and new jobs as they fan out across three continents for the next 12 months.

We invite you to find out about the individuals taking part in this program, the organizations who are sponsoring them and the people they are helping.
